    Thanks for visiting Plantbook.

    Harpephyllum caffrum is a host plant to several moth and some butterfly species. This is a totally natural phenomenon and the plant will recover from it so there is no need to take any action in this regard.

    Use an organic fertiliser and lots of compost to enrich your soil. As this is naturally a forest species, it will benefit from a thick layer of organic mulch such as leaf litter twigs, etc.

  2. Hi Glenice, I planted four of these on my smallholding well spaced and have grown from 100mm to around 850mm in nearly a year. We live in Hopefield Western Cape. I notice that the some leaves are being eaten which seems like the Eggar moth. We get them around here. Is there a remedy to control this? Can’t seem to find much info on this. And secondly what fertizer would suffice as we have sandy soil here? Maybe if you have some good literature I would appreciate.

    Regards

    Thanks for visiting Plantbook.

    As far as we’re aware, the fruit is not toxic to dogs. The fruit usually falls when ripe and, in most cases, birds get to it on the tree before it drops.

  4. Is there any evidence of the fruit being toxic to dogs? Does it contain cyanide like other plum spp?

  5. Hi Jane

    Thanks for visiting Plantbook.

    Your tree could be losing its new growth as a sign of stress – heat, wind or lack of water are the more common issues.

    It may be best to take a cutting of a branch to your local nursery for assistance.

  6. My Wild plum tree of about 3-4m sprouted new leaves & young branches for a few weeks but they are now falling off (October) & the top branches do not have any new growth
    How to tell if the tree has a disease & how to treat please?
    I cannot see any thing on the fallen leaves or the tree

  7. Hi Peter

    Thanks for visiting Plantbook.

    Harpephyllum caffrum (Wild plum) are susceptible to frost especially in exposed areas so it is likely that yours have been affected.

    Give your trees a little more time and they should recover over summer.

  8. I planted two 50L Wild plum trees last Spring. The trees established themselves very well, but they seem to have taken some strain through the Johannesburg winter (Midrand); we’re now a few weeks into Spring and I’m just a bit concerned that they haven’t yet got any green leaves – all my other indigenous trees do already; I’ve given them a good watering over the past 2 weeks. Does the tree suffer normally through winter?

  9. Hi Antonie

    Thanks for visiting Plantbook.

    I love plants and prefer not to offer advice on the removal of a large indigenous tree without seeing the conditions.

    Perhaps consult with an arborist as your tree seems to nearing maturity and may not cause any issues.

  10. Our wild plum is about 15 years old. It’s topping 4-5m. It is planted 4m from our house, but it’s only a metre from the vibracrete wall and the neighbour’s foundations are probably 3m away. It recently lifted the paving down the side of our house. I extracted a piece of root about 3 m long. I estimate the total length of that root is 7-8 m. It hadn’t turned to the foundation, but I’m concerned that it will cause issues for us or our neighbour. Should we remove the tree?

  11. Hi Karin

    Thanks for visiting Plantbook.

    You can experiment with your germination mix as this will provide additional nutrition to your seedlings before planting out.

    Remember to record your proportions so that you can replicate or make adjustments in future.

  12. When germinating tree seed can you mix a small amount of kraal manure with the sand and compost?

  13. Hi Sharon

    Where a species has separate sexes on individual trees, the male trees do not bear fruit. That is why your tree has never borne fruit.

  14. Hi Glenice,

    I have a male tree as it has never borne fruit and it it 12 years old.
    . What do you think it coukd be?

    Thanks so much

  15. Hi Sharon

    Thanks for visiting Plantbook.

    Could the orange substance be bits of fruit that the birds are dropping as they eat? If this is the case, it’s normal for this time of year when the trees are fruiting.

  16. I have a Harpephyllum caffrum and noticed when we park our cars under it they get covered in an orange colored substance? It is hard to get off.
    Its this normal of this tree?

  17. Hi, my wild plum is about 6 years old. Since a few months ago gum is snoozing from the trunk – about 20cn from the ground. It is currently bearing fruit and it does not look different from previous years. Is it a problem or what can I do to treat the problem – i.e. if it is a problem. If you can provide me of a link to read it is also fine. Thanks

  18. Hi Clint

    Thanks for visiting Plantbook.

    Most plants will go through transplant shock especially if transplanted under stressful conditions which include:
    – Hot or windy conditions
    – Active growing period (i.e. summer)
    – Water stress
    – The size of the plant. Larger and older plants tend to undergo more stress than younger ones.

    Harpephyllum caffrum are generally strong so your plant should recover. Remember to water it regularly to keep the soil moist.

  19. Does the wild plum transplant well? I have recently transplanted a tree and within a week it is looking very sad. The tip growth is black and the leaves are wilting. Do you know if it will recover?

  20. Hi Louise

    Thanks for visiting Plantbook.

    Harpephyllum caffrum can have an aggressive root system and should not be planted less than 4m from any structure.

    Note that root systems can vary depending on the growing conditions, so this serves as a guide.

  21. Good day to you, I need information about the roots of the wild plum tree as my neighbor is in the process of
    cutting down his tree, he says the tree has invasive roots and the roots are growing underneath the foundation of his garage. The tree has been growing for over 20 years and I cannot find any information about the root system, please help!!

  22. Hi Piet

    Thanks for visiting Plantbook.

    Harpephyllum caffrum will grow at the coast as its natural habitat is along the east coast of South Africa.

    We’ve seen specimens growing well in Gauteng in areas which experience heavy frost. So the tree may work in Bloemfontein. I would advise you to ask your local nursery who will have more experience species suitable for your conditions. If you do go ahead, remember to protect the trunk of your tree for its first 2-3 cold seasons. Another alternative to consider would be a wild olive (Olea europaea subsp. africana).

  23. I want to plant the wild plum (harpephyllum caffrum in a corner of my stand as a shadow tree at the coast. The corner fence is formed by a concrete fence on one side and a brick fence on the other. Will the roots break the fences?
    Will the tree grow in Bloemfontein where frost is sometimes severe?

  24. Hi Shelton

    Thanks for visiting Plantbook.

    The choice of tree will depend on the space available.

    Harpephyllum caffrum requires at least 6m from any structure to avoid damage.

    Other alternatives to consider are:
    Heteropyxis natalensis (Lavender tree)
    Kiggelaria africana (Wild peach)
    Ilex mitis (Cape holly)
    Apodytes dimidiata (White pear)

  25. Hi Jonathan

    Thanks for visiting Plantbook.

    It isn’t normal for Harpephyllum caffrum to experience excessive loss of leaves in summer.

    Your tree could be under some stress like lack of water.

    Look for signs of new growth. New leaves generally grow on the tips of the branches.

    Without knowing the age and location of the tree, I’ll have to advise you to perhaps take a cutting to your local nursery for further advice.

  26. What would you recommend for a large shading tree in a driveway? Want to plant it in the corner of our driveway but don’t want to worry about damage to our walls or paving…

  27. Hi Leigh

    Hmmm… this sounds interesting. Perhaps take a cutting of the growth to your nearest nursery to help with identification.

  28. I think mine is a Japanese plum and this winter an odd sprouting appeared. I figured it was from the changes in weather we had been experiencing. Now that the tree is beginning to bear fruit, this sprouting has really taken off and it is definitely not the same plant. Looks kind of like a jade plant. But whatever it is, it happened on its own. Any ideas what it is? How it happened? Do I need to cut it off ?

  29. Hi Marie

    Thanks for visiting Plantbook.

    The most obvious difference is that the female trees bear fruit and the male trees do not. Until they start producing fruit, there is no noticeable difference.

    Yes, this tree can survive frost. Ensure that your newly planted tree is protected for the first two winters.

  31. Hi Gail

    Thanks for visiting Plantbook.

    Unfortunately there is nothing that I know of to stop a plant from bearing fruit.

    As a consolation, it only occurs at a certain period of the year.

    In the meantime, enjoy the shade and take a moment to appreciate the birds and the fact that you’re providing for nature!

  32. Is there anything to give the tree to stunt the ability to bare the fruit? The birds are making a mess everywhere and the sticky fruit stains the ground. Love the tree, but the fruit is a nuisance.
